The sign above says that the Silver Line to Dudley is this exit.
The sign on the wall says “No Silver Line Access”.
How is a tourist supposed to know that there are multiple Silver Lines, at two locations, and the upper sign refers to only the SL4 line to Dudley, which boards at street level, and the “No Silver Line Access” sign refers only to the other lines that board underground: the SL1 to Logan Airport, the SL2 to the Design Center, the SL3 to Chelsea , and the SLW to Silver Line Way?
